In 2003 , the policy of “ rejuvenating the northeastern china ” let the northeastern china , the old industry base , start to fresh industry charm , and the economy of china establish the opening situation of tripartite balance of force , namely , rejuvenating the northeastern china , developing the western china and fully speeding ahead of the economy in southeastern china , thus the chinese economy will continue reform and opening to the outside world , and increase strongly 2003年“振兴东北”的政策出台，东北这个中国的老工业基地开始焕发其久违的工业魅力，随之而来中国经济形成了“三足鼎立”的开放态势，即振兴东北老工业基地、西部大开发进程加快与东南经济全速前进，中国经济将迎来新一轮的改革开放与强劲增长。
In the late seventies of the twentieth century , the finite element method ( fem ) for rsrw was introduced , so that , the structural deformation is closely linked with the balance of force , and consequently the simulation of complicated properties and processes become possible . however , the study of rsrw using this method has not integrated so far , people commonly take static load but not dynamic load and interaction between water and reinforced soil ( rs ) body into consideration in analysis 70年代后期才开始的加筋土结构有限元分析将结构变形协调与力的平衡结合起来,使某些复杂的性质及过程的模拟成为可能,但至今为止加筋土挡墙结构特性的数值分析研究仍处于初期阶段,如考虑动力荷载作用较少,一般都不考虑水的作用,或仅将水作为一种外部荷载以静止水压力的形式作用在结构上。
